Jeff King 6cf378f0cb docs: stop using asciidoc no-inline-literal
In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.

It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:

  1. The source is much easier to read when the literal
     contains punctuation. You can use `master~1` instead
     of `master{tilde}1`.

  2. They are less error-prone. Because of point (1), we
     tend to make mistakes and forget the extra layer of
     quoting.

This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).

Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:

  - HTML rendering used the ellipsis character instead of
    literal "..." in code examples (like "git log A...B")

  - some code examples used the right-arrow character
    instead of '->' because they failed to quote

  - api-config.txt did not quote tilde, and the resulting
    HTML contained a bogus snippet like:

      <tt><sub></tt> foo <tt></sub>bar</tt>

    which caused some parsers to choke and omit whole
    sections of the page.

  - git-commit.txt confused ``foo`` (backticks inside a
    literal) with ``foo'' (matched double-quotes)

  - mentions of `A U Thor <author@example.com>` used to
    erroneously auto-generate a mailto footnote for
    author@example.com

  - the description of --word-diff=plain incorrectly showed
    the output as "[-removed-] and {added}", not "{+added+}".

  - using "prime" notation like:

      commit `C` and its replacement `C'`

    confused asciidoc into thinking that everything between
    the first backtick and the final apostrophe were meant
    to be inside matched quotes

  - asciidoc got confused by the escaping of some of our
    asterisks. In particular,

      `credential.\*` and `credential.<url>.\*`

    properly escaped the asterisk in the first case, but
    literally passed through the backslash in the second
    case.

git-archive(1)
==============
NAME
----
git-archive - Create an archive of files from a named tree
SYNOPSIS
--------
[verse]
'git archive' [--format=<fmt>] [--list] [--prefix=<prefix>/] [<extra>]
[-o | --output=<file>] [--worktree-attributes]
[--remote=<repo> [--exec=<git-upload-archive>]] <tree-ish>
[<path>...]
DESCRIPTION
-----------
Creates an archive of the specified format containing the tree
structure for the named tree, and writes it out to the standard
output. If <prefix> is specified it is
prepended to the filenames in the archive.
'git archive' behaves differently when given a tree ID versus when
given a commit ID or tag ID. In the first case the current time is
used as the modification time of each file in the archive. In the latter
case the commit time as recorded in the referenced commit object is
used instead. Additionally the commit ID is stored in a global
extended pax header if the tar format is used; it can be extracted
using 'git get-tar-commit-id'. In ZIP files it is stored as a file
comment.
OPTIONS
-------
--format=<fmt>::
Format of the resulting archive: 'tar' or 'zip'. If this option
is not given, and the output file is specified, the format is
inferred from the filename if possible (e.g. writing to "foo.zip"
makes the output to be in the zip format). Otherwise the output
format is `tar`.
-l::
--list::
Show all available formats.
-v::
--verbose::
Report progress to stderr.
--prefix=<prefix>/::
Prepend <prefix>/ to each filename in the archive.
-o <file>::
--output=<file>::
Write the archive to <file> instead of stdout.
--worktree-attributes::
Look for attributes in .gitattributes in working directory too.
<extra>::
This can be any options that the archiver backend understands.
See next section.
--remote=<repo>::
Instead of making a tar archive from the local repository,
retrieve a tar archive from a remote repository.
--exec=<git-upload-archive>::
Used with --remote to specify the path to the
'git-upload-archive' on the remote side.
<tree-ish>::
The tree or commit to produce an archive for.
<path>::
Without an optional path parameter, all files and subdirectories
of the current working directory are included in the archive.
If one or more paths are specified, only these are included.
BACKEND EXTRA OPTIONS
---------------------
zip
~~~
-0::
Store the files instead of deflating them.
-9::
Highest and slowest compression level. You can specify any
number from 1 to 9 to adjust compression speed and ratio.
CONFIGURATION
-------------
tar.umask::
This variable can be used to restrict the permission bits of
tar archive entries. The default is 0002, which turns off the
world write bit. The special value "user" indicates that the
archiving user's umask will be used instead. See umask(2) for
details. If `--remote` is used then only the configuration of
the remote repository takes effect.
tar.<format>.command::
This variable specifies a shell command through which the tar
output generated by `git archive` should be piped. The command
is executed using the shell with the generated tar file on its
standard input, and should produce the final output on its
standard output. Any compression-level options will be passed
to the command (e.g., "-9"). An output file with the same
extension as `<format>` will be use this format if no other
format is given.
+
The "tar.gz" and "tgz" formats are defined automatically and default to
`gzip -cn`. You may override them with custom commands.
tar.<format>.remote::
If true, enable `<format>` for use by remote clients via
linkgit:git-upload-archive[1]. Defaults to false for
user-defined formats, but true for the "tar.gz" and "tgz"
formats.
ATTRIBUTES
----------
export-ignore::
Files and directories with the attribute export-ignore won't be
added to archive files. See linkgit:gitattributes[5] for details.
export-subst::
If the attribute export-subst is set for a file then git will
expand several placeholders when adding this file to an archive.
See linkgit:gitattributes[5] for details.
Note that attributes are by default taken from the `.gitattributes` files
in the tree that is being archived. If you want to tweak the way the
output is generated after the fact (e.g. you committed without adding an
appropriate export-ignore in its `.gitattributes`), adjust the checked out
`.gitattributes` file as necessary and use `--worktree-attributes`
option. Alternatively you can keep necessary attributes that should apply
while archiving any tree in your `$GIT_DIR/info/attributes` file.
EXAMPLES
--------
`git archive --format=tar --prefix=junk/ HEAD | (cd /var/tmp/ && tar xf -)`::
Create a tar archive that contains the contents of the
latest commit on the current branch, and extract it in the
`/var/tmp/junk` directory.
`git archive --format=tar --prefix=git-1.4.0/ v1.4.0 | gzip >git-1.4.0.tar.gz`::
Create a compressed tarball for v1.4.0 release.
`git archive --format=tar.gz --prefix=git-1.4.0/ v1.4.0 >git-1.4.0.tar.gz`::
Same as above, but using the builtin tar.gz handling.
`git archive --prefix=git-1.4.0/ -o git-1.4.0.tar.gz v1.4.0`::
Same as above, but the format is inferred from the output file.
`git archive --format=tar --prefix=git-1.4.0/ v1.4.0^{tree} | gzip >git-1.4.0.tar.gz`::
Create a compressed tarball for v1.4.0 release, but without a
global extended pax header.
`git archive --format=zip --prefix=git-docs/ HEAD:Documentation/ > git-1.4.0-docs.zip`::
Put everything in the current head's Documentation/ directory
into 'git-1.4.0-docs.zip', with the prefix 'git-docs/'.
`git archive -o latest.zip HEAD`::
Create a Zip archive that contains the contents of the latest
commit on the current branch. Note that the output format is
inferred by the extension of the output file.
`git config tar.tar.xz.command "xz -c"`::
Configure a "tar.xz" format for making LZMA-compressed tarfiles.
You can use it specifying `--format=tar.xz`, or by creating an
output file like `-o foo.tar.xz`.
